Thanks for sharing! Did you make the nest and do you have an easy recipe to follow? I want to put one up this winter but still unclear on where and how high and how big of one I should make or purchase.
I'm told natural holes are better. I was thinking of taking a hollow dead section of old tree laying in the woods and cutting it in half lengthwise so I can more easily hollow out the inside, then create the correct hole size, then screw the halves back together and mount it. I don't know how to hollow out an existing dead tree that is upright yet.
I read they find the holes on the wing by spotting the color difference between the bark and the hole with its dark cavity behind it.
but I also ready they scout their nests in the fall so I might be too late.
